What Makes Paris's Water Unique?

Local geology and source profile

Source: LakeTDS: 295.5 mg/LpH: 7.7

The Paris Drinking Water System, operated by the County of Brant for the community of Paris, Ontario, serves around 15,000 residents in Paris and nearby areas of Brant County. Its primary source is the Grand River, with water drawn and treated at the Paris Water Treatment Plant. This surface water supply is sometimes blended with groundwater. The treatment process involves standard steps like filtration, disinfection, and fluoridation before the water reaches homes. Compliance with Ontario's Safe Drinking Water Act is detailed annually by the County of Brant Public Works department.

The Grand River watershed, a substantial 6,800 square kilometer area flowing into Lake Erie, passes over Paleozoic bedrock rich in Ordovician-Silurian limestones and dolomites. Nearby geological features, including the Niagara Escarpment with its karst topography, encourage mineral dissolution. This bedrock composition gives the water a distinctly hard quality, as calcium and magnesium ions are released from the carbonate rocks. While the river's flow offers some dilution, seasonal variations and agricultural runoff can increase mineral content.

This level of hardness significantly contributes to scale buildup, particularly impacting appliances like water heaters, dishwashers, kettles, and washing machines. These calcium deposits reduce efficiency and shorten the lifespan of your equipment. You might also notice white residue on plumbing fixtures and find that soap doesn't lather well, potentially leading you to use more detergent. To combat these issues, consider deliming your appliances every six to twelve months. For a more comprehensive solution, installing a water softener is strongly recommended to extend the life of your machines and improve cleaning effectiveness.

Geology & Source: Grand River watershed; Paleozoic limestone and dolostone formations (Salina, Bertie) contribute high calcium and magnesium, resulting in hard water.
